Xubuntu 20.04 USB Keyboard and Mouse Not Working

r06ue1 · 04-29-2021, 01:38 PM

Kernel 5.4.0-72

Here's what I have tried:

USB Keyboard and Mouse work in all ports (KB/Mouse ports, USB 2.0 ports, USB 3.0 ports) in the BIOS settings and GRUB menu.

USB Keyboard and Mouse with the OS running (or in recovery mode) works only in the USB 3.0 ports.

This appears to have started after upgrading from 18.04.02.

I would be okay with just using the USB 3.0 port, however, the mouse is constantly double clicking on everything due to the speed and lowing the sensitivity to the lowest setting has not helped.

Since both work in the KB/Mouse ports in the BIOS settings and GRUB menu, the problem appears to be an OS one. Any ideas would be greatly appreciated by a Linux newb.

Thanks in advance!

To see whether it's a problem at the OS level or the x windows level. Try something like ...

sudo od -t a /dev/input/mouse0

It should spit out some binary nonsense every time you move or click on the mouse (and only then).

Also try a different mouse.

I heard of a similar problem occurring due to Wayland. Though I expect, with Xfce, you would be running xorg, it's worth looking into.

The following command will tell you which display server you are running:

Quote:

loginctl show-session $(loginctl | grep $(whoami) | awk '{print $1}') -p Type

If it's xorg, then this is the wrong track. But if it's Wayland, try to log into an xorg session and see if the problem goes away.

It's Xorg:

Type=x11

This is a relatively new motherboard so I'd hate to think that it is driver related but that is the only thing coming to mind. It seems that nothing I plug in to those USB ports works (I tried a USB 2.0 drive in one of the USB 2.0 ports and it didn't light up or show in the list of devices using lsblk). I'll try to find out the controller info and see if those drivers were excluded from the kernel builds.

Try this. On all USB ports obviously. It's a simple test, should provide definite troubleshooting info.

In the USB 3.0 port, I get output, in any others (2.0, 1.1) nothing. When I move the mouse to one of those ports, it disappears from the list of USB devices.

Code:

Move back to 3.0 port, works fine again:

I thought maybe the OS was powering off the USB ports (since plugging in a USB drive also fails on those ports) so I tried adding usbcore.autosuspend=-1 to the grub command line but that didn't fix the problem. I'm thinking that this is a driver bug and I need to report it.

Any other kernels available for install? I'd try something not 5.4.x.

Are the USB2 ports working at all?

Yes, in BIOS and GRUB, as soon as the OS boots up, they shut down. Goes for the 1.1 USB ports also, only the 3.0 work while the OS is running.

^ so it's not actually a mouse/keyboard problem?

Searching on that helped a lot, thanks.

Adding "iommu=soft" to GRUB fixed the problem.
